1. Gold Processing. The first step in gold smelting involves processing the gold ore. The ore containing gold once mined from the earth is processed by separating gold minerals from the crude matter holding the ore together. The gold ore is then pulverized using pressure to create very fine particles.

In gold sand gravity separation, when roughing with a chute or jig, the coarse concentrate is usually enriched by a shaker with a very high ore ratio, its recovery rate can reach more than 98%, and directly get the final concentrate and abandoned tailings. The above process is generally used in small-scale, low-grade gold sand concentrators.

When you mix the finely powdered gold-bearing rock with some mercury, the gold within the rock dissolves, to form what's called a gold amalgam. The next step in the process is to separate the gold amalgam from any 'unreacted' mercury. We did this by squeezing the crude amalgam through a small piece of chamois leather.
